List of descriptive cataloging elements for use in bibliographic control of nonprint materials.
Bibliographic control of audiovisuals or nonprint materials, generated at the point of publication, is almost nonexistent. The authors address this problem and present an outline of bibliographic elements that nonprint producers need to include on each individual production.

The networked environment and the challenge of change.
The way for librarians to manage the environment of the future is to hold fast to their traditional skills and professional abilities. The challenges in the future environment include technology adoption, copyright, scholarly communication, and the role of professional medical societies. Four major areas in which librarians have skills valuable in this environment are the organization of knowledge, quality assurance of information, custodianship, and user instruction.

Mechanization of library procedures in the medium-sized medical library. IV. Physical characteristics of the acquisitions-cataloging record.
Acquisitions-Cataloging records stored on magnetic tape by the Washington University School of Medicine Library were examined to determine frequency and average length of record components and their alphabetization requirements in a book catalog. Data from this study of 4,708 records will be used in adaptation of the Library's computer-based cataloging system to greater machine capabilities. The first of these two papers compares measurements found for WUSML records with those reported in studies of conventional catalog cards. The number of sorting positions used to alphabetize entries and causes of sort failure are examined in the second paper (Number V) which will be found on page 71 of this issue of the BULLETIN.
Virtual shelves in a digital library: a framework for access to networked information sources.
OBJECTIVE: Develop a framework for collections-based access to networked information sources that addresses the problem of location-dependent access to information sources. DESIGN: This framework uses a metaphor of a virtual shelf. A virtual shelf is a general-purpose server that is dedicated to a particular information subject class. The identifier of one of these servers identifies its subject class. Location-independent call numbers are assigned to information sources. Call numbers are based on standard vocabulary codes. The call numbers are first mapped to the location-independent identifiers of virtual shelves. When access to an information resource is required, a location directory provides a second mapping of these location-independent server identifiers to actual network locations. RESULTS: The framework has been implemented in two different systems. One system is based on the Open System Foundation/Distributed Computing Environment and the other is based on the World Wide Web. CONCLUSIONS: This framework applies in new ways traditional methods of library classification and cataloging. It is compatible with two traditional styles of selecting information searching and browsing. Traditional methods may be combined with new paradigms of information searching that will be able to take advantage of the special properties of digital information. Cooperation between the library-informational science community and the informatics community can provide a means for a continuing application of the knowledge and techniques of library science to the new problems of networked information sources.
Government documents and the online catalog.
Prior to planning for implementing the NOTIS system, the Vanderbilt Medical Center Library had not fully cataloged its government publications, and records for these materials were not in machine-readable format. A decision was made that patrons should need to look in only one place for all library materials, including the Health and Human Services Department publications received each year from the central library's Government Documents Unit. Beginning in 1985, these publications were added to the library's database, and the entire 7,200-piece collection is now in the online catalog. Working with these publications has taught the library much about the advantages and disadvantages of cataloging government documents in an online environment. It was found that OCLC cataloging copy is eventually available for most titles, although only about 10% of the records have MeSH headings. Staff time is the major expenditure; problems are caused by documents' irregular nature, frequent format changes, and difficult authority work. Since their addition to the online catalog, documents are used more and the library has better control.
A union catalog of monographs: another approach.
The rationale for and the production of the 1977 TALON Union Catalog of Monographs are described. The 158,859 records include the existing machine-readable records for six health sciences libraries plus the cataloging of six others, converted by matching other data bases and by keypunching. The method and costs of production are discussed. Use of Computer-Output-Microfiche (COM) significantly decreased the cost and time required for publication. The $.076 unit cost per entry, with both author and title access for the COM method, is almost one-half the unit cost for the previous method which offered only main-entry access. The TALON Catalog compares favorably with the Midwest Medical Union Catalog. The addition of the title index significantly increases its usefulness. However, the unique feature of the TALON Catalog may be its machine-readable form which offers the potential for quantitative analyses of health sciences library collections. Such data may be essential for rational management of limited library funds.
Toward a whole cDNA catalog: construction of an equalized cDNA library from mouse embryos.
The construction of a cDNA library containing all genes without redundancy is one of the major technical challenges for biology. Toward this goal, we have developed an equalized (normalized) cDNA library from mRNA pools derived from mouse embryos that cover the entire period of mouse ontogenesis. Colony hybridization analyses with 11 genes showed the reduction of abundance variation from at least 6000-fold in the unequalized S-library to approximately 33-fold in the EIII-library, which was constructed after three cycles of equalization procedure. Limiting dilution PCR analyses with 26 tissue-specific genes showed the reduction of abundance variation from at least approximately 1,000,000-fold in the S-cDNA mixture to approximately 100-fold in the EIII-cDNA mixture. Based on these analyses, we estimate that at least 15,000 independent cDNA clones are included with little redundancy in the EIII-cDNA library. This will be a useful resource for mouse biology as well as the mouse genome project.
CATALOGING AND CLASSIFYING FOR A MEDICAL LIBRARY.

Classification systems used in medical libraries.
The present study identifies the classification systems used in 941 libraries. It explores the reasons behind the choice of the National Library of Medicine Classification by 589 libraries. Reclassification procedures were investigated through a questionnaire sent to twenty-five libraries that have changed to NLM since 1959. Statistics and replies are given on: the classification systems employed prior to reclassification; the use of broad or specific Library of Congress class numbers in the LC schedules outside the scope of the NLM schedules; the number of catalogers in each library doing the reclassification; the use of cut-off dates for retrospective materials; the adoption of MeSH headings; user preference; and cost differences. Chief reasons for the change to NLM proved to be local circumstances, currency, arrangement of subclasses by NLM, its dovetailing with the LC Classification, and reliance upon nationally centralized cataloging services.
Audiovisuals and non-print learning resources in a health sciences library.
The MD undergraduate program at McMaster University, based entirely on self-instruction, requires the provision of all kinds of learning resources. How these are assembled and made available is described. Emphasis is placed on the practical library problems of cataloging, shelving, maintenance, and distribution of audiovisual materials including pathology specimens and 'problem boxes' as well as the more usual films, videotapes and slide/tape sets. Evaluation is discussed briefly.
